Categories
All articles need categories to easily find and manage them. To add a category, just add it to the bottom of a page like a link. Adding a pipe and a character after it will change what character it is put under in the category. For eponymous articles in a category, use *.
For a list of categories, see Special:Categories. For a list of pages that need them, use Special:UncategorizedPages.
